Kate Winslet, Christoph Waltz, Jodie Foster and John C. Reilly fight over how it ought to be done in "Carnage." George Clooney in "The Descendants," Matt Damon in "We Bought a Zoo" and Sandra Bullock in "Extremely Loud & Incredibly Close" are worried about doing it alone. Viola Davis does it for other people in "The Help." Demián Bichir does it as an immigrant in "A Better Life." Nick Nolte is trying to do it over sober in "Warrior." And Tilda Swinton has blood-soaked proof that she has done it all terribly wrong in "We Need to Talk About Kevin."
